Why do Sri Lankan natural resources are being challenged in terms of maintaining the sustainability? a. COVID-19 has led to extinct of some natural species. b. Increased awareness in environmental protection, Due to COVID-19 situation c. Deforestation due to increased demand for land, a considerable number of species are threatened species d. Deforestation and damages occur to natural resources are beyond the human control

The sustainability of Sri Lankan natural resources is being challenged due to several reasons:

a. COVID-19 and Extinction of Species: While it's not accurate to say that COVID-19 has led to the extinction of some natural species, the pandemic has certainly disrupted conservation efforts and could potentially lead to increased threats to biodiversity.

b. Increased Environmental Awareness: The COVID-19 situation has indeed increased awareness about environmental protection. However, this awareness needs to be translated into action to effectively protect and sustain natural resources.

c. Deforestation: This is a major challenge to the sustainability of natural resources in Sri Lanka. The increased demand for land leads to deforestation, which in turn threatens a considerable number of species. Deforestation also disrupts ecosystems and contributes to climate change.

d. Uncontrollable Damage: Some damages to natural resources are beyond human control, such as those caused by natural disasters. However, human activities often exacerbate these damages, for example, by contributing to climate change which increases the frequency and intensity of extreme weather events.

Therefore, maintaining the sustainability of Sri Lanka's natural resources requires addressing these challenges through measures such as enforcing stricter environmental regulations, promoting sustainable land use practices, and enhancing conservation efforts.
