(Originais Teachy 2023) - Question Easy of Environmental science

Consider a small town located near a forest. The town's population has been growing rapidly, leading to an expansion of its boundaries into the forest area. As a result, a significant portion of the forest has been cleared to make way for new homes and businesses. Understanding the fundamental principles of ecosystems and human impact on them, explain how this expansion might affect the biodiversity of the forest.
a.
The expansion of the town into the forest can have several impacts on the forest's biodiversity, including habitat loss, fragmentation, edge effects, the introduction of non-native species, and pollution. These impacts can lead to reductions in the number of species (species richness), the abundance of species (species evenness), and the genetic diversity within species.
b.
The expansion of the town into the forest will have no significant impact on the forest's biodiversity, as species will adapt to the new conditions.
c.
The expansion of the town into the forest will increase the forest's biodiversity, as new species will be introduced.
d.
The expansion of the town into the forest will only affect the forest's biodiversity if non-native species are introduced, otherwise, the biodiversity will remain the same.
e.
The expansion of the town into the forest will only affect the forest's biodiversity through pollution, other factors such as habitat loss, fragmentation, and edge effects will have no significant impact.

Urbanization and industrialization have accelerated human action in nature, increasing the emission of greenhouse gases and contributing to climate change. How can the general circulation of the atmosphere and climate patterns be affected by these human actions? Additionally, describe the main characteristics of landscapes transformed by human labor through the development of agriculture and the industrialization process, and explain how human interaction with nature has changed with the emergence of cities.

Acid rain is a phenomenon that occurs as a result of air pollution, which makes the water falling from the sky more acidic. This rain is the result of the mixture of gases such as sulfur dioxide and nitrogen dioxide, released in large quantities into the atmosphere by the burning of fossil fuels. What happens to plants and animals when exposed to acid rain?
