The geography of Malaysia includes both the physical and the human geography of Malaysia, a Southeast Asian country made up of two major landmasses separated by water—Peninsular Malaysia to the West and East Malaysia to the East—and numerous smaller islands that surround those landmasses. Peninsular Malaysia is on the southernmost part of the Malay Peninsula, south of Thailand, north of Singapore and east of the Indonesian island of Sumatra; East Malaysia comprises most of the northern part of Borneo island, and shares land borders with Brunei to the north and Indonesian Borneo to the south.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Sundaland is a biogeographical region of South-eastern Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Bali, Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the Malay Peninsula on the Asian mainland.
The Kii Peninsula is the largest peninsula on the island of Honshū in Japan. It is named after the ancient Kii Province. The peninsula has long been a sacred place in Buddhism, Shinto, and Shugendo, and many people would visit from all over Japan as part of the Kumano religious practices.

The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean with an average depth of 5.8 m (19 ft). It lies between the southeastern tip of India and the west coast of Sri Lanka, in the Coromandel Coast region. The chain of low islands and reefs known as Ram Sethu, which includes Mannar Island, separates the Gulf of Mannar from Palk Bay, which lies to the north between India and Sri Lanka. The estuaries of Thamirabarani River and Vaippar River of South India and the Malvathu Oya of Sri Lanka drain into the Gulf. The dugong is found here.
Blast fishing, fish bombing, dynamite fishing or grenade fishing is a destructive fishing practice using explosives to stun or kill schools of fish for easy collection. This often illegal practice is extremely destructive to the surrounding ecosystem, as the explosion often destroys the underlying habitat that supports the fish. The frequently improvised nature of the explosives used, and undetonated charges, means danger for fishermen and divers as well, with accidents and injuries.
The Australian environment ranges from virtually pristine Antarctic territory and rainforests to degraded industrial areas of major cities. Forty distinct ecoregions have been identified across the Australian mainland and islands. Central Australia has a very dry climate. The interior has a number of deserts while most of the coastal areas are populated. Northern Australia experiences tropical cyclones while much of the country is prone to periodic drought. This dry and warm environment and exposure to cyclones, makes Australia particularly vulnerable to climate change -- with some areas already experiencing increases in wildfires and fragile ecosystems.
The wildlife of Malaysia is diverse, with Malaysia being a megadiverse country. Most of the country is covered in rainforest, which hosts a huge diversity of plant and animal species. There are approximately 361 mammal species, 694 bird species, 250 reptile species, and 150 frog species found in Malaysia. Its large marine territory also holds a great diversity of life, with the country's coastal waters comprising part of the Coral Triangle.
The environment of Malaysia is the biotas and geologies that constitute the natural environment of Malaysia. Malaysia's ecology is megadiverse, with a biodiverse range of flora and fauna found in various ecoregions throughout the country. Tropical rainforests encompass between 59% and 70% of Malaysia's total land area, of which 11.6% is pristine. Malaysia has the world's fifth largest mangrove area, which totals over a half a million hectares.
The Semporna Peninsula is a peninsula in Tawau Division, Sabah, Malaysia. It consists of coastal areas and numerous isolated hills and mountains rising to over 305 metres (1,001 ft). The Peninsula is also considered as a volcanic arc of the region with several volcanoes active during the Holocene period is located on the area.
Climate change is having a considerable impact in Malaysia. Increasing temperatures are likely to greatly increase the number of heatwaves occurring annually. Variations in precipitation may increase the frequency of droughts and floods in various local areas. Sea level rise may inundate some coastal areas. These impacts are expected to have numerous environmental and socioeconomic effects, exacerbating existing environmental issues and reinforcing inequality.
The Dent Peninsula is a peninsula in eastern Sabah, Malaysia. It consists of hills and broad coastal areas. The Peninsula is also previously considered as a volcanic arc of the region which have since migrated southward to Semporna Peninsula.
The Sandakan Peninsula is a peninsula in Sandakan District, Sabah, Malaysia. It consists of broad coastal and forested areas.
The Kudat Peninsula is a peninsula in northern of Sabah, Malaysia. It consists of high coastal with windy shorelines and swamp areas. The peninsula become the area where the South China Sea meets the Sulu Sea.
The Klias Peninsula is a peninsula in western of Sabah, Malaysia. It consists of coastal wetlands which become the largest mangrove and nipa swamp area in Sabah's west coast and serves as a major nurturing ground for fisheries resources in the Brunei Bay and Kimanis Bay.
Sri Lanka exhibits a remarkable biological diversity and is considered to be the richest country in Asia in terms of species concentration.
Bengkoka Forest Reserve is a protected forest reserve in Pitas District of Kudat Division, on the Bengkoka Peninsula in Sabah, Malaysia. It was designated as a Class 1 Protection Forest by the Sabah Forestry Department in 1984. Its area is 6,270 hectares (62.7 km2). The reserve is low-lying.
