Environmental legislation is very strict, and every tourism project must undergo an environmental review and a lengthy process of consultations with the public and conservationists. The Seychelles is a world leader in sustainable tourism. The end result of this sustainable development is an intact and stable natural environment, which attracts financially strong visitors (150,000 in 2007) rather than short-term mass tourism. Since 1993 a law guarantees the citizens the right to a clean environment and at the same time obliges them to protect this environment. The country holds a record for the highest percentage of land under natural conservation—nearly 50% of the total land area of the Seychelles.

Like many fragile island ecosystems, the Seychelles saw the loss of biodiversity during early human history, including the disappearance of most of the giant tortoises from the granitic islands, the felling of coastal and mid-level forests, and the extinction of species such as the chestnut flanked white eye, the Seychelles Parakeet, the Seychelles Black Terrapin and the saltwater crocodile. However, extinctions were far fewer than on islands such as Mauritius or Hawaii, partly due to a shorter period of human occupation (since 1770). The Seychelles today is known for success stories in protecting its flora and fauna. The rare Seychelles Black Parrot, the national bird of the country, is now protected.

The granitic islands of Seychelles are home to about 75 endemic plant species, with a further 25 or so species in the Aldabra group. Particularly well-known is the Coco de Mer, a species of palm that grows only on the islands of Praslin and neighbouring Curieuse. Sometimes nicknamed the "love nut" because of the shape of its fruit which, with the husk removed, presents a "double" coconut resembling a woman's buttocks, the coco-de-mer produces the world's heaviest seed pods. The jellyfish tree is to be found in only a few locations on Mahe. This strange and ancient plant in a genus of its own (Medusagynaceae) has resisted all efforts to propagate it. Other unique plant species include the Wright's Gardenia Rothmannia annae found only on Aride Island Special Reserve.

The freshwater crab genus Seychellum is endemic to the granitic Seychelles, and a further 26 species of crabs and 5 species of hermit crabs live on the islands.

The Aldabra Giant Tortoise now populates many of the islands of the Seychelles. The Aldabra population is the largest in the world. These unique reptiles can be found even in captive herds. It has been reported that the granitic islands of Seychelles supported distinct species of Seychelles giant tortoises; the status of the different populations is currently unclear.

There are several unique varieties of orchids on the Islands.

Seychelles hosts some of the largest seabird colonies in the world. In the outer islands Aldabra and Cosmoledo are home to the largest numbers. In granitic Seychelles the largest numbers are on Aride Island including the world's largest numbers of two species.

The marine life around the islands, especially the more remote coral islands, can be spectacular. More than 1,000 species of fish have been recorded. Since the use of spearguns and dynamite for fishing was banned through efforts of local conservationists in the 1960s, the wildlife is unafraid of snorkelers and divers. Coral bleaching in 1998 has unfortunately damaged most reefs, but some reefs show healthy recovery (e.g. Silhouette Island).

Although multinational oil companies have explored the waters around the islands, no oil or gas has been found. In 2005, a deal was signed with US firm Petroquest, giving it exploration rights to about 30,000 km2 around Constant, Topaz, Farquhar and Coëtivy islands until 2014. Seychelles imports oil from the Gulf in the form of refined petroleum derivatives at the rate of about 5,700 barrels per day (910 m3/d). In recent years oil has been imported from Kuwait and also from Bahrain. Seychelles imports three times more oil than is needed for internal uses because it re-exports the surplus oil in the form of bunker for ships and aircraft calling at Mahé. There are no refining capacities on the islands. Oil and gas imports, distribution and re-export are the responsibility of Seychelles Petroleum (Sepec), while oil exploration is the responsibility of the Seychelles National Oil Company (SNOC).

The main natural resources of the Seychelles are fish, copra, cinnamon, coconuts, salt and iron.
