Write any 5 human activities that have threatened our environment.
Match the following actions with the correct category:
Actions | Category
---|---
Using a refillable water bottle instead of buying disposable plastic bottles | Reduce
Turning off lights and electronics when not in use. | Reuse
Donating old clothes and toys to a thrift store instead of throwing them away | Recycle
Recycling paper, plastic, and glass instead of throwing them away |
Explain the environmental impact of each of the following actions:
* Using a reusable grocery bag instead of a plastic bag.
* Leaving the water running while brushing your teeth.
Answer (2)
Human activities like deforestation, pollution, and plastic waste threaten the environment significantly. Actions such as using reusable bags and conserving water can help mitigate these impacts. By understanding and changing our behaviors, we can protect our planet for future generations.
;
Five human activities that have threatened our environment include:
Deforestation : This involves cutting down trees on a large scale, which reduces biodiversity and contributes to climate change by increasing the amount of carbon dioxide in the atmosphere.
Pollution : The release of pollutants into air, water, and soil can harm wildlife and human health. Examples include industrial waste, car emissions, and plastic waste.
Overfishing : This depletes fish supplies faster than they can naturally recover, threatening marine ecosystems.
Use of Fossil Fuels : Burning coal, oil, and gas releases greenhouse gases, leading to global warming and climate change.
Land Conversion for Agriculture : Turning forests and grasslands into farmland raises greenhouse gas emissions and reduces natural habitats.
For the given actions and categories:
Using a refillable water bottle instead of buying disposable plastic bottles matches with Reduce as it minimizes waste and resource consumption.
Turning off lights and electronics when not in use matches with Reuse , although it's more accurate to include this under conserving resources, saving energy, and reducing environmental impact.
Donating old clothes and toys to a thrift store instead of throwing them away matches with Reuse as it extends the life of items.
Recycling paper, plastic, and glass instead of throwing them away clearly falls under Recycle .
The environmental impact of specific actions:
Using a reusable grocery bag instead of a plastic bag : This reduces plastic waste in landfills and oceans. Plastic bags are made from non-renewable resources, take centuries to decompose, and pose threats to wildlife if ingested by animals.
Leaving the water running while brushing your teeth : This wastes a significant amount of water, which is a critical resource. Conserving water reduces the energy needed for water treatment and distribution, thereby decreasing one's environmental footprint.
