Ecosystem services

Ecosystem services

1. Are the procceses thorough wich natural ecosystems an their living communities sustain and fullfil human life

2. Practical uses of biodiversity and ecosystem services

   • Ecosystem services include purifying air and water, replen fishing oxygen, pollinating plants and dispersing their seeds, providing wildlife habitat, decomposing wastes, controlling erosions and flooding, controlling pests and providing recreational opportunities.

3. Use of some ecosystems good directly

   • Logging, Fishing, hunting.
     • Logging In some undeveloped countries they log trees to use it for furnitures or to create a source of heat
     • Fishing Almost everyone is able to buy food of this marine environment
     • Hunting for food In some undeveloped countries they still hunt for their own food, hunting in land environments or even marine ones .

4. Ecosystem services also benefit people indirectly

   • Erosion and flood control. Plants block wind that blows away loose soil. Their roots stabilize the soil and increase its ability to hold water, re ducing both soil erosion and flooding.
   • Soil Formation Farming grasslands have turned into one of the most productive agricultural regions in the world Soil, with its diverse community of decomposer they play a major role (bacteria, fungi, worms, many insects, and others) in breaking down wastes with nutrients. People rely on this to decompose products from industry, sewage, agriculture, found in soil
   • Climate Regulation By providing shade, reducing temperature, and serving as windbreaks that reduce evaporation, plant communities have a major impact on local climates. Forests dramatically influence the water cycle, returning water to the atmo sphere through transpiration
   • Genetic Resources According to the United Nations Food and Agriculture Organization 75% of human food is supplied by only 12 food crops. wild plants have some genes that might be transferred into crops to increase productivity and provide greater resistance to disease, drought, and salt accumulation in irrigated soil.
   • Recreation Each year in the U.S., about 350 mil billi lion visitors flock to protected public lands such as nation Orl al parks and wildlife refuges.
