<h3>How can I help with conservation?</h3>
- Buy recycled paper avoiding the death of more trees
- Have a recycling bin for paper, plastic, metal and glass, to reduce the environmental damage in waste and for the waste to be reused
- Recycle toner and ink cartridges from empty printers, to avoid polluting rivers and streams.
- If possible buy remanufactured cartridges, avoiding environmental impact
- Recycle old newspapers, avoiding the death of more trees.
<h3>What is the evidence for evolution?</h3>
- Anatomy. Species may share similar physical features because those features were present in a common ancestor (homologous structures).
- Molecular biology. DNA and genetic code reflect the common ancestry of life
With this information, we can conclude that Ecology is concerned with the living beings on the planet and their relationships with each other and with the environment.
