1 People Are Working to Protect Ecosystems Environmental Awareness is Growing: In 1872, the world’s first national park was established (Yellowstone), starting our Country’s Conservation effort. This grew rapidly in the 1960’s and in the ’70’s many laws were passed to preserve & protect the environment. –CONSERVATION= process of saving or protecting a natural resource Conserving Resources Protects Ecosystems: –SUSTAINABLE Practices= ways of living & doing business that use natural resources without using them up. Developing new technologies, reducing resource use, & creating less waste are 3 ways to practice this. Think Globally, Act Locally

2 LOCAL EFFORTS Grass roots efforts, occur on a local level & are mainly run by volunteers. (Think globally, act locally). Often the efforts of a few citizens gather the support & interest of so many people, they form a larger organization. These groups work to bring about change by communicating with politicians, publishing articles, or taking to the news media.

3 Federal Efforts The U.S. government works with scientists to write laws that make sure companies & citizens work together to conserve natural resources & keep healthy ecosystems. In the 1960’s NEPA (National Evironmental Policy Act) made the protection of natural ecosystems a national goal. The Clean Air Act & Clean Water Act improved control of pollutants put into air & water. The EPA (Environmental Protection Agency) enforces all Federal Environmental Laws.

4 Federal Efforts Con’t. Over the past decades, chemical waste from factories has piled up in landfills & polluted water sources. In 1980, citizen awareness led to the Superfund Program: goal is to identify dangerous areas & clean up the worst sites. Federal agencies oversee this. State environmental laws also apply to companies in that state. Dozens of countries have met to discuss concerns about clear- cutting, water pollution, & endangered species. The United Nations Environment Programme encourages sound environmental practices worldwide.

6 Improving Resource Use Some farmers are using sustainable methods to protect land & give nutritious food: 1/3 of US farmers do conservation tillage (plant seeds without plowing soil, cutting soil erosion by 90%) U.S. Forest Service encourages cutting selectively instead of clear-cutting, allowing for rapid regrowth & biodiversity preservation. Energy companies are looking for alternative fuels to fossil fuels. (geothermal uses Earth’s internal heat for energy, Hydropower uses falling/flowing water, wind, & solar are other alternative sources for non-polluting energy.

7 Reducing Waste & Pollution Mass transit moves large groups of people at the same time (bus). This reduces amount of pollution. Carpooling does a similar thing. Home reductions: fluorescent light bulbs (less electricity), energy- efficient appliances, lower thermostat in winter & raise it in summer, add insulation around doors & windows, and recycle. Some materials are recycled into same product (metal & glass) or new products (fleece jacket from recycled soda bottles, or cereal box from paper.

8 Think Globally, Act Locally Visitors to an ocean beach may see sign like one on right. Remind people that small actions (avoiding sandpiper nests) make a difference in the preservation of ecosystems. Providing Earth’s growing population with clean water & air, & with energy for warmth & transportation are some of the tasks. We’re still learning of interactions in ecosystems & how they effect our world. In coming years, protection of ecosystems will stay a major challenge. Think globally: understand the effects of society’s decisions about resources, development & transportation Act Locally: become involved in efforts to reduce use of limited resources & restore ecosystems.
