In two or more complete sentences, describe a scenario where human activities are related to an increase or decrease in blodiversity in an ecosystem. Write your answer in the essay box below
Answers
Answer:
Deforestation and loss of green areas so that factories can use those areas for their benefit, exploiting the natural resources around them decrease an ecosystem's biodiversity. The invasion of industrial areas and excessive use of their natural resources causes a disbalance in the ecosystem because the plants, water, nutrients, minerals, amongst other elements, are used by industries killing animals and species, reducing populations due to pollution, and lack of food.
Explanation:
An ecosystem is a system where animals and living organisms, such as plants or bacteria, live together with nonliving elements. Living organisms interact with each other and with nonliving ones to keep the system balanced.
We can define biodiversity as the variety of living things that exist in an ecosystem.
Human activities like deforestation and the building of big factories near areas with large amounts of natural resources lead to the killing of many species. As industries kill in excess species, or they pollute an ecosystem's soil and water, the species' population decreases. Asa result, there is a disbalance in the ecosystem.
A human activity that increases biodiversity is the protection of endangered animals or laws to protect natural areas where there are many species of plants and animals that are of high importance for the planet.

Dear Mr. President,
Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.
- (Explain what you learned in class today ) I don't know what you were taught in class so you have to figure what to put here.
Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.
