Most solid waste deposited in landfills is composed primarily of tin, steel, or aluminum cans, glass bottles, plastic bottles, and other plastic goods. Electronic waste such as batteries, computer parts, and old household appliances is increasingly found in the landfills, as is medical waste in the vicinity of health clinics (Posch et al 2015; Maharjan and Gustafsson 2019; Faulon and Sacareau 2020)
Local lodge owners and waste management organizations have treated this waste as “burnable garbage” since around 2010, as other options were either absent or perceived to be too costly. This particular nomenclature suggests that once burned, the problem is solved, when in fact the burning catalyzes a multitude of new health and environmental problems in the process (Maharjan and Gustafsson 2019)

These were the steps taken to achieve the project's objectives included:

You can do it purely for fun or keep a life list—a birding term for the running list that bird enthusiasts keep of all the different birds they see. Whatever your goal, you’ll be rewarded by the sights and sounds of beautiful and interesting feathered creatures, especially come spring and fall. But along with all the fun and wonders. 
We all must be aware and responsible in engaging in this type of activities. Promoting awareness and environmental protection/habitats of birds and/or animals. One of which that promotes thats is; Mindful Birding organization.

“Dispose of waste properly.” (Montana Fish, Wildlife, and Parks, accessed 2014)
“A birder must understand that they are in the bird’s world, and in order to preserve this world for 
years to come, things that are out of place, like wrappers and bottles, should not be left behind. This 
simple rule also extends itself to include picking up trash that may be found on trails.” (Lake Region

The crisis has crystallized the importance of tourism as a development pathway for many countries to decrease poverty and improve their economies. "Responsible travel to natural areas that conserve the environment, sustains the well-being of the local people, and involves interpretation and education”. Such traveling can be created thanks to an international network of individuals, institutions, and the tourism industry where tourists and tourism professionals are educated on ecological issues.
