Water conservation refers to the practice of using water wisely and efficiently to reduce waste and preserve water resources. It involves the responsible use, management, and protection of water sources to ensure their availability for present and future generations. Water conservation encompasses various strategies and activities aimed at reducing water consumption and promoting sustainable water use.

The importance of water conservation in today’s world cannot be overstated. Here are some key reasons why water conservation is crucial:

1. Scarcity of Freshwater: Freshwater resources are finite and face increasing pressure due to population growth, urbanization, and climate change. By conserving water, we can help alleviate water scarcity issues and ensure a sustainable supply of clean water for human needs, agriculture, and ecosystems.

2. Environmental Protection: Conserving water helps protect aquatic ecosystems, rivers, lakes, and wetlands. Adequate water flow is essential for maintaining the health of these habitats, supporting diverse wildlife, and preserving biodiversity.

3. Energy Conservation: Energy is required for treating, transporting, and heating water. By conserving water, we indirectly reduce energy consumption and the associated carbon emissions. Water conservation can contribute to mitigating climate change and promoting a more sustainable energy future.

4. Economic Benefits: Water scarcity can lead to economic challenges, particularly in areas heavily reliant on agriculture and industries that require substantial water supplies. By conserving water, we can enhance water security, reduce costs associated with water treatment and distribution, and promote economic stability.

5. Drought Resilience: Droughts are becoming more frequent and severe in many regions around the world. Water conservation measures such as rainwater harvesting, efficient irrigation systems, and responsible water use can help communities become more resilient to drought conditions.

6. Personal Responsibility: Practicing water conservation is a way to exercise personal responsibility and contribute to the collective effort of preserving our planet’s natural resources. Conserving water is an act of environmental stewardship that individuals, households, and communities can undertake to make a positive impact.

Overall, water conservation is crucial for ensuring water security, protecting the environment, mitigating climate change, and promoting sustainable development. It requires a combination of individual actions, efficient technologies, and responsible water management practices at various levels, from households and businesses to governments and water authorities.

Recycling paper instead of throwing it in the trash is important for several reasons:

1. Conservation of natural resources: Paper is primarily made from wood pulp, which comes from trees. By recycling paper, we can reduce the demand for fresh trees and preserve forests. Recycling one ton of paper can save approximately 17 trees, as well as other resources like water, energy, and chemicals used in the paper production process.

2. Energy savings: Producing paper from recycled fibers requires much less energy compared to using virgin materials. Recycling paper can save up to 60-70% of the energy needed to manufacture paper from new sources. Conserving energy helps reduce greenhouse gas emissions and mitigates climate change.

3. Waste reduction: Paper constitutes a significant portion of municipal solid waste. By recycling paper, we can divert it from landfills, where it would decompose and contribute to the production of methane, a potent greenhouse gas. Additionally, reducing the amount of waste sent to landfills extends their lifespan and reduces the need for additional landfill space.

4. Pollution reduction: The paper manufacturing process involves various chemicals, including bleaches and dyes, which can be harmful to the environment if not properly managed. Recycling paper reduces the need for these chemicals, minimizing pollution and the associated environmental impacts.

5. Recycling paper is an environmentally responsible choice that helps conserve resources, reduce waste, and minimize pollution. By participating in paper recycling programs, individuals and communities can make a positive impact on the environment and work towards a more sustainable future.

(1+x)/3=2 (since lcm is same)

(1+x)=2*3=6

x=6-1

x=5

The sum of the angles in triangle=180

let missing angle=x°

so 40°+60°+x=180°

100+x=180

x=180°-100°

x=80°

Therefore missing angle is 80°
