World Nature Conservation Day, observed every July 28, highlights the importance of caring for our planet and the creatures living on it.

Conservation entails caring for all of Earth's resources, from plants and animals to minerals, water and air. As explained by National Geographic, the goal of conservation is to use nature sustainably and ensure that they persist for future generations.

"Conservation means the wise use of the earth and its resources for the lasting good of men," said Gifford Pinchot who was known as the father of American conservation.

Unfortunately, humans have been consuming the Earth's natural resources at an unsustainable rate, which has greatly affected biodiversity.

"The main factors driving biodiversity loss include habitat destruction, climate change, invasive species, overexploitation, and pollution," Nat Geo noted.

World Nature Conservation Day is observed to highlight the importance of conserving all the Earth's natural resources. Although it may seem a daunting task, there are actually a few simple things that we can do everyday to do our part in keeping our planet healthy.

For instance, with concerns about the world's dwindling water resources, we can do our part by simply turning off the tap when not in use, or even making small changes to lessen our usage. Using rainwater for irrigation and shortening shower time are just some of the small things we can do to contribute.

Reducing, reusing and recycling are still among the simplest things we can do to help reduce our waste, whether it's e-waste from our many electronic devices or the plastics we use. People can also look for simple ways to reduce their energy consumption by carpooling with co-workers instead of using separate vehicles, or making sure to shut of electricity when it's not in use.

Those who have extra time may volunteer for efforts such as community clean-up drives, or perhaps in conservation groups, zoos or aquariums.

People who have a bit of space in their backyards may even make it more "wildlife friendly" by planting native species to help provide resources for the wild animals. Avoiding wasteful and harmful products such as chemical pest control may also help.

On this day, let's look at some quotes about conservation that may just encourage you to take action. (Courtesy: Good Reads, Kidadl and Brainy Quote)
