Human Activities Harmful towards Food:
1. Overconsumption: Excessive consumption of food leads to food wastage and scarcity for others.
2. Food Wastage: Improper storage, transportation, and handling of food result in significant wastage.
3. Pollution: Pollution from industries and agriculture can contaminate food sources.
4. Deforestation: Deforestation leads to habitat loss for wildlife, impacting food sources.

Conservation Methods for Better Food Sustainability:
1. Reduce Food Waste: Proper planning, storage, and consumption can help reduce food wastage.
2. Sustainable Agriculture: Practices like crop rotation, organic farming, and water conservation can help conserve food sources.
3. Educating Consumers: Awareness campaigns about the importance of food conservation can help promote sustainable practices.
4. Food Preservation Techniques: Canning, freezing, and drying are effective methods to prolong the shelf life of food.
5. Support Local Farmers: Buying locally sourced food reduces the carbon footprint associated with transportation.
6. Implementing Food Policies: Governments can enforce regulations to prevent food wastage and promote sustainable food practices.
By adopting these conservation methods, we can ensure a more sustainable and secure food supply for present and future generations.
