True or False: Small environmental changes can significantly impact fish and wildlife survival rates.

1. True

2. False

3. Only with large changes

4. Only in urban areas

The correct answer is: True

Small environmental changes can indeed have significant impacts on fish and wildlife survival rates. This is primarily because aquatic and terrestrial species are often sensitive to fluctuations in their habitat conditions, such as temperature changes, water quality, availability of food sources, and other ecological factors. Even minor alterations in these conditions, such as pollution, changes in land use, or the introduction of invasive species, can disrupt the delicate balance necessary for the survival of various species. For instance, a slight increase in water temperature could affect the breeding cycles of fish, while the introduction of a new pollutant might harm sensitive aquatic organisms. Similarly, small changes in land use, like urbanization or agricultural expansion, can reduce the habitats available for wildlife, leading to decreased population sizes. These types of impacts can cascade through ecosystems, affecting entire food chains and altering community dynamics. Therefore, recognizing that small environmental changes can lead to substantial consequences is crucial for effective wildlife management and conservation strategies.
