Essay 3: Paragraph 1 - How global climate change affects wildlife

Wildlife is greatly impacted by global climate change. Specific requirements for living conditions must be met in order for a species to survive in its environment, and global climate change has increased the chance of extinction for thirty percent of all species by producing variations in living conditions.  First of all, global climate change causes changes in temperature, making it harder for certain species to survive in their natural habitat.  The temperature in the environment must be appropriate for the species living there.  For example, several aquatic species need cold water to survive, but their populations are decreasing as global climate change causes water temperatures to rise.  The interaction among wildlife is changing as a result of global climate change as well. Wildlife is dependent on various food sources in the environment, and the change in climate has resulted in the migration of many species, making it difficult to find essential food sources.  For example, birds depend on insects and plants for survival, but the climate change causes the plants to bloom either too early or too late, and the insects are not always ready for the birds to eat.  When the bird migrates and arrives to its new destination, it is often times unable to find the food it needs.

  3. I really like this topic, I think that more people need to be aware of what causes global climate change and what its effects are on the wildlife.
