Global warming is the ongoing rise of the average temperature of the Earth's climate system which has various negative effects.
Overpopulation creates an increased demand for energy as well as having negative effects on our environment and ecosystems.
Overfishing is the removal of a species of fish from a body of water at a rate that the species cannot replenish, resulting in those species becoming underpopulated in that area.
This will lead to a Marine Ecosystem imbalance with time.
Water is essential for agricultural production and food security. It is the lifeblood of ecosystems, including forests, lakes, and wetlands.
Overpopulation affects our water and this has negative outcomes.
Over-cultivation is the practice of excessive farming on a piece of land to the point of degradation of the soil as well as the land itself.
Climate change is likely to both increase electricity demand for cooling in the summer and decrease electricity, natural gas, heating oil, and wood demand for heating in the winter.
Finding reusable energy sources can be our first step towards conserving our environment.
How will climate change affect the production of clean energy?
e.g.: solar, wind, water
New infrastructure investments may be necessary to meet increased energy demand.
e.g.: nuclear power plants
Healthy ecosystems and rich biodiversity are fundamental to life on our planet.
Even small changes in average temperatures can have a significant effect upon ecosystems.
The inter-connected nature of ecosystems means that the loss of species can have knock-on effects upon a range of ecosystem functions.
e.g. bees go extinct
Climate change will affect mountain and lowland ecosystems, the diversity of wildlife, and the distribution of freshwater.
e.g.: forest fires
Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favorable conditions.
e.g.: natural habitat disappearing
