Human activity concentrates naturally occurring compounds until they become hazardous. When rainwater or wastewater from homes runs into storm drains, it picks up these hazardous compounds and deposits them into waterways. Man-made compounds like DDT and cleaners are also introduced into the marine environment this way. Much of human runoff results from individuals’ day-to-day activities.
Biostimulants do not stimulate life, as their name might mislead one to believe; instead, they do more harm than good. Sewage is organic and breaks down via bacterial decay. The decay process depletes available oxygen and suffocates local animal life. Additionally, the chemical breakdown produces ammonia and hydrogen sulfide. These chemicals are toxic to fish, even in low concentrations. Bacteria and other contaminants may be consumed by shellfish, which then become hazardous to humans or other animals if consumed. Some forms of algae thrive on the nutrients created by biostimulants and can overgrow into algae blooms or “red tides.”
Oil is introduced into waterways through spills like the massive Deepwater Horizon spill in the Gulf of Mexico on April 20, 2010. Oil production also leads to the seepage of oil into the marine ecosystem, as does rainwater runoff. Oil floats on the surface of the water, coating and suffocating any marine life that touches the water’s surface. Oil also prevents oxygen from permeating from the air into water, and thereby suffocates life that may not even directly touch the oil.
As humans travel the earth’s waters, we leave our mark. Despite regulation, we toss debris over the sides of ships, and lose things like containers and fishing nets overboard. This debris is eaten by fish and water mammals and can eventually kill them.
Nuclear power plants and other industrial outlets use water as a coolant. The heated water is disposed of directly into waterways where it increases the temperature of the body of water. This, again, stimulates the dangerous growth of algae blooms.

Human activity has had a drastic effect on the world’s natural resources. Even casual day to day activities like washing the car, doing dishes, taking a shower or watering the lawn can have consequences. Urban runoff is the largest source of marine pollution today.
Wastewater from homes and rainwater carrying chemicals and concentrated naturally occurring compounds flows into storm drains and makes its way into local waterways and eventually to the ocean. Activities like hosing down the sidewalks, not cleaning up pet waste, tossing trash onto the ground or into storm drains, and over-watering lawns create additional incidences of urban runoff, which in turn creates more marine pollution.
Toxins and sediments from urban runoff can lead to many problems that are devastating to waterways:
When urban runoff creates problems in the oceans and other waterways, it’s not just marine life that is affected. Many problems arise for humans, as well, including:
Although industry was a big polluter in the past, today most urban runoff is caused by everyday people, which means that the solution is up to each and every one of us. You have plenty of options to decrease your contribution to urban runoff. Never dump anything down a storm drain. Do not hose off paved surfaces like your driveway or sideway — use a broom instead. Pick up litter so that it doesn’t get washed down a storm drain the next time it rains, and don’t contribute to the problem by littering yourself. Clean up after your pet. In many places this isn’t just a good idea, it’s the law! Dispose of hazardous waste properly. Look up your local laws and find your local hazardous waste collection site. Many household cleaners are considered hazardous waste. Be aware of this and read labels before tossing things out. Avoid using pesticides or fertilizers on your lawn. Take your car to a car wash center that recycles its water. If you notice your car leaking, fix it quickly. Use a rain barrel to collect water to use when watering your garden, preventing additional runoff. Working together, we can reduce the amount of marine pollutants we produce as a society.

Today, the decision to purchase environmentally friendly products over products potentially hazardous products has become a more popular decision than ever. Many are surprised to learn that there are a number of products available in our own kitchen pantries that will work effectively to clean our kitchens and bathrooms, remove mold, and keep our laundry clean and fresh. These environmentally friendly products can be used without any fear of water contamination.
Baking soda effectively cleans and deodorizes everything from your kitchen sink to your stove. For tough stove top stains, mix baking soda with a little bit of water to create a paste, and use it as you would use any commercially made cleanser. Products from around your home, such as salt, flour, and vinegar mixed together, will clean brass; other products, such as lemon juice and salt, will safely remove tarnish from copper.
Many people are unaware of the environmentally friendly products that can be used to polish their furniture. To make eco-friendly furniture polish, mix together two parts of olive oil and one part of lemon juice. If you do not have any olive oil, you can substitute vegetable oil. Apply the mixture with a soft cloth and then buff your furniture to a beautiful shine. To double-check that will not harm your wood, you may want to test this cleaner in an inconspicuous spot before applying it to an entire piece of furniture.
Many bathroom cleaners contain pollutants that contaminate water. Many environmentally friendly products that can effectively clean and deodorize your bathroom can be found in your own home. An open dish of vinegar or a potpourri-warmer filled with cloves or cinnamon will absorb odors. Sprinkling baking soda on a sponge will effectively remove mold from grout. For mold and mildew on shower curtains, a sponge soaked in lemon juice can wipe mold and mildew off of shower curtains without contaminating water or creating pollution. Hard water and lime deposits can be difficult to remove from any bathroom surface; most products that are made for this purpose are not eco-friendly. However, you can loosen the lime and hard water deposits with white vinegar, making them easy to clean with baking soda and a sponge. There are even more ways to boost your efforts by conserving water in your bathroom.
Environmentally friendly products from around the house can also ease our work in the laundry room. As an eco-friendly alternative to commercial fabric softeners, add one cup of white vinegar to the final rinse cycle of your laundry. However, chlorine bleach and vinegar should never be mixed; if you are washing whites with bleach, an alternative fabric softener would be 1/4 cup of baking soda added to the rinse cycle instead.
You can also help the environment by conserving your water usage at home!

In today’s society, many of us have become accustomed to the sight of birds and marine animals struggling for life on an oil-slicked beach after a massive oil spill. We have also become more aware of the devastating effects that automobile emissions have on the atmosphere. Some may even recall the hellish image of burning oil wells in Kuwait spewing black clouds into the sky after the Gulf War. However, one danger of the petroleum industry has not received much attention in recent years: the petroleum pollutants created by industrial production and refinement.
For crude oil to be converted into its many useful forms, such as gasoline, diesel, and kerosene, it must be processed extensively in large chemical refineries. These refineries are full of toxic chemicals that, especially in under-regulated third-world nations, often leak into local atmospheres and water systems. Each year the petroleum-refining industry produces hundreds of millions of pounds of pollutants, pollutants that consist of over one hundred different toxic chemicals, many of which find their way into the air, water, and land. Some of the petroleum pollutants released by refineries include sulfuric and hydrofluoric acid, ammonia, chlorine, benzine, lead, and mercury, all of which harm human health.
When concentrated in high enough levels, these petroleum pollutants harm and disrupt ecosystems and human communities. Runoff from refineries and unlined waste ponds harms–or even destroys–local ecosystems whenever it enters the local water system. Often little can be done to undo the harm caused by this pollution. Sometimes the pollutants directly affect agriculture and livestock, harming animals and local economies, as well as humans themselves. Unprotected populations near petroleum facilities often see higher rates of cancer, dermatitis, fungal infection, headaches, and nausea.
Transporting products to and from refineries often results in massive spills, which are also very damaging to local environments. Additionally, the creation of refineries and the roadways to and from these facilities has been responsible for the irreparable destruction of huge tracts of virgin wilderness, including the highly threatened Amazon Rainforest. As petroleum production continues, levels of petroleum pollutants will only increase and, in some areas, will eventually reach levels at which massive environmental damage may become irreversible.
The best thing that the average citizen can do to help stop the problems associated with petroleum pollutants is to become aware of these problems. This awareness alone will impact how you use petroleum and its products and will help you to inform others. You may also take further steps through donation or volunteer work to help mitigate the damage already caused; however, the threat of petroleum pollutants will only continue as long as the petroleum industry remains profitable.

Transporting Water
When you live in a developed country where clean, potable water comes out of the tap whenever you want, it’s easy to take a luxury like clean water for granted. In many parts of the world people must carry water over long distances. Over one billion people currently do not have access to clean drinking water. Efforts are being made to help support the people in those countries.
Half of all rural households in Africa do not have easy access to potable water. In places like Ethiopia, carrying water for the family is primarily the job of the women and children, who must often be carrying water on their heads and shoulders in large jugs that can cause shoulder and back injuries over time. Families may travel miles to retrieve river water that may not be suitable for consumption. Then they carry the water–enough to drink, cook, and wash with–back. Some villages have hand pumps, but these may only work intermittently and are difficult to fix once broken. Sometimes private water carriers bring water to homes, but this service charges a fee that many people cannot afford.
Many charitable organizations and non-profits devote money and resources to helping people who do not have easy access to drinking water. These include UNICEF, WaterAid, Charity: Water, World Concern, The Water Project, Global Water, Operation Hydros and our friends at water.org .
Some of the projects involve services like digging wells and establishing water pumps, or building spring protection systems, rainwater catchment, and biosand filters, or rehabilitating previous water systems that are no longer in good repair.
Technological advances are being made for communities that still rely on carrying water from the source to help make that job easier. One of these advances is the Q Drum, a rolling barrel that is filled and then pulled along with a cord. The Q Drum has been used successfully in Africa, and was recently used during the cholera outbreak in Haiti. Another successful advance is the “Pumpkin,” a device that is worn like a shoulder bag and can carry up to 15 liters of water. The tubes in this device also act as a filter.
The best solution to the problem of carrying water varies, depending on one’s location. One must take into account variables like climate and geography. In some communities, a good solution is providing a working hand pump. In others, a good solution is providing a way to collect rainwater and keep it from sinking into the ground. Traditions die hard, and some families insist upon continuing to travel long distances for water. In these cases, a device that eases the task of carrying water will be the most helpful.
If you want to make a huge difference in others’ lives, you can get involved. Volunteer with or donate to a charity that helps provide clean drinking water to communities in need.

Water conservation in landscaping, referred to as xeriscaping, has many benefits for the yard, the environment, and the property owner. There are several lawn alternatives to typical turf that will provide adequate groundcover, improve curbside appeal, and reduce the environmental impacts of typical lawns. The most effective lawn alternative method will depend upon many factors. Several possibilities include ornamental grasses, flowers, shrubs, groundcover, clover, and permanent structures. Assessing the climate, space in which to work, soil needs, and budget are all important to the process of incorporating a xeriscape.
Ornamental grasses are often drought resistant and require little maintenance. They can be found in varieties that are slow creepers or taller in shape and spread quickly. Nature Hills Nursery has thorough explanations of each type of grass and clearly shows in which zones they will thrive.
Flowers and shrubs can add color, texture, and form to the xeriscape. Before planting either of these lawn alternatives the soil needs to be assessed. Sandy soil will not drain as well, clay soil might hold too much water, and some soils are acidic. The authors of HGTVpro.com suggest focusing on two factors: type and substance. When the goal is to reduce water consumption of the lawn, choose flowers and shrubs that are appropriate for the soil and are drought resistant.
Groundcover refers to plants that grow at low heights, often assisting in erosion control with reduced water needs, as lawn alternatives. This type of cover can be achieved with clover, an invasive, short plant type that requires little water or care. According the University of Minnesota Extension Service, at one time clover was actually added to many lawn seed options because of its durable and soft characteristics. It can easily and quickly fill in bare spots in lawns, mows easily, and can boast attractive white flowers.
Permanent structures such as pathways, seating areas, and ground patios can also be lawn alternatives in a xeriscaping project. They don’t require fertilizers, water, or heavy weed control, which all reduce the overall impact on the soil and environment.
Joyce Latimer, Extension Specialist at Virginia Tech, suggests creating a plan for reducing water consumption and seeking lawn alternatives. Observe the area, note the wind direction, sun and shade zones, and erosion concerns. Choose plants that are clearly labeled for the specific planting zone and use mulch to maintain the areas around plantings, reducing water needs and preventing soil loss from wind and rain. Carefully researching and planning lawn alternatives will aid in water consumption, land conservation, and can save time with regular maintenance.

Water and erosion work together to transport materials from their natural location to another place. Water and wind erosion are the most common forms of erosion. Warming temperatures throughout the world, neglect and carelessness on the part of man, and overuse of land are all contributing factors to erosion. Marked changes in weather patterns and pollution can also be contributing factors to erosion. While man is partially responsible for some of the causes of erosion, man also has the ability to offer practical solutions to counteract the effects of erosion.
Erosion is simply the movement of soil or other such materials from one place to another through natural means such as water or wind. Water aids the erosion process by exerting a force with each movement. Water does not work independently of wind to cause erosion. While it is the water that actually transports the materials away, wind often causes the movement of the water. Water and erosion work together with the force of the wind to carry materials away. The end result, in some cases, is damage that is not easy to correct or reverse. Many coastal areas are subject to water erosion. Many of the world’s most popular beaches wouldn’t exist if it wasn’t for efforts by man to undo the continuous effects of water and erosion.
Water and erosion can be categories into six basic types of erosion. Rain splash erosion refers to the detachment and movement (by air) of small soil particles caused by the impact of raindrops on land or soil. Sheet erosion refers to the movement of soil particles over the natural slopes of the land caused by rainfall. Rill erosion refers to the development (over time) of small flow paths where the water travels along to cause erosion. Gully erosion refers to hollowed out areas that become lower than the surrounding land. This allows water to collect and remove soil. An example of this is an old rural road that over time becomes lower than the surrounding area. Bank erosion refers to the wearing away of banks/streams of a river. Shoreline erosion refers to the movement of soil/sand from shore areas due to the actions of the waves. Ice erosion is the movement of large bodies of ice (such as glaciers and ice sheets) causing damage along the way.
Studies show climate change has been gradual, often just a few degrees or a portion of a degree. This may seem insignificant, but a change in the Earth’s temperature by even a few degrees may result in a shift of weather patterns. Climate change increases the overall impact of water and erosion in some instances. Some areas of the world not usually prone to storms now face reduced shorelines and beaches due to erosion. A change in weather patterns also means a change in precipitation patterns. In other words, some areas receive more rainfall than usual, directly causing soil erosion.
Soil erosion caused by water can be prevented in several ways. One way is to plant trees and other barriers to prevent an unobstructed path for water to move soil. Other ways include crop rotation, run-off barriers, contour farming/crop rotation and man-made efforts.

If you’re thinking about planting a garden, you should consider a few important questions: What kind of soil do you have? How much sunlight is available? How much rain does the area get?
For a lower-maintenance, greener garden, consider using as many native plants as possible. Native plants won’t require lugging home expensive soils and fertilizers, they won’t require extensive watering, and they are more suitable for organic gardening.
Native plants are the flora that evolved naturally within the local ecology (together with animals, fungi and microbes) to create the local ecosystem. Native plants are the foundation upon which the rest of the ecosystem is built. Indigenous plants provide food and shelter for local wildlife and do not force out other species that belong in the local ecosystem. Non-native plants can harm the local system, becoming invasive and forcing out or harming other local plant or animal life.
Native plants are adapted to local conditions, including rainfall. Whereas a non-native species may come from a more tropical climate, requiring daily watering, a local plant should never need watering beyond what is naturally provided, unless the season is unusually dry.
A little research on the Internet should quickly answer this question. Use a search engine with your location (for example, Pacific Northwest or New England) and search for “native plants.” Most regions have a local native gardening society that can help you decide what to plant. You can also take a walk in a local wildlife area, though not necessarily a park, as that may have been planted with imports. Observe what is growing naturally. Use a notebook and a camera to capture plant life that has caught your eye.
Visit a local nursery. Avoid the large, big-box home improvement stores; instead, browse small, local businesses. These are usually run by people who know their stuff and are eager to share it with interested listeners. Another bonus of gardening with native plants is that you will also save a lot of money on products like soil, pesticides and fertilizer. Native plants are already adapted to local conditions and have evolved to withstand local insects and diseases.
