The difference between plant and animal cells lies in the structural differences. Plant cells are rectangular whilst animal cells are round and plant cells contain chloroplasts, a cell wall, and vacuoles while animal cells do not. Also, plants give off oxygen and take in carbon dioxide given off by animals. Plants cells have cell walls and other structures that differ from those of animals. Animal cells do not have cell walls and have different structures than plant cells.

Public transportation, cleaner energy and recycling would lead to a reduction in pollution and burning fossil fuels.
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.
Humans impact on the environment can manifest as:
- overpopulation- natural resources are over used, and habitats cannot support human communities;
- urban communities also expand by cutting down trees in deforestation- this leads to erosion and flooding;
- burning fossil fuels- this reduces air quality and adds carbon dioxide to the environment leading to global warming;
- pollution- adding contaminants to the atmosphere, waterways, soil etc.
