The Essay on How Humans Affect The Environment. The human population is expected to double in the next 50 years, and the ever-growing global population needs vast amounts of food, energy and raw materials. We cannot continue to get our food, energy and raw materials in the way we do now without damaging the earth’s environment beyond repair.
In addition to the resident livestock, 15,000-20,000 migratory sheep and goats also grazed in the alpine pastures of the reserve for about 4-5 months between the months of May and October every year, which has profound effects on the biodiversity of the forest ecosystem, thus leading to the changes in species composition, species behaviour, and vegetation structure of the reserve.
Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.
The Global biodiversity assessment warns, “Unless actions are taken to protect biodiversity, we will lose forever the opportunity of reaping its full potential benefit to humankind.” Effective and implementable methods of stopping further genetic erosion and fostering the rehabilitation of degraded ecosystems in mega biodiversity regions are the need of the hour.
Biodiversity is the amount of variety of life on Earth. It is the number of different species of plants, animals, and microorganisms. It includes organisms from Earth’s vastly different ecosystems, including deserts, rainforests, coral reefs, grasslands, tundra, and polar ice caps. Our biodiversity is very important to the well-being of our.
Our eagle example also demonstrates another aspect of diversity. The Pacific Northwest represents a unique ecosystem. The Gulf Coast of Florida is another unique ecosystem with different characteristics. Having a rich variety of ecosystems, what biologists call ecosystem diversity, constitutes another important level of biodiversity.
The biodiversity of microbes, fungi, and other smaller organisms is important in decomposing waste matter. Organic material in nature, such as leaves, logs and twigs, and dead animals and insects, is all degraded and decomposed by the biodiversity of organisms in the ecosystem.
