Explain the poem "Lament" by Gillian Clarke.

For the green turtle with her pulsing burden,

in search of the breeding ground.

For her eggs laid in their nest of sickness.

For the cormorant in his funeral silk,

the veil of iridescence on the sand,

the shadow on the sea.

For the ocean’s lap with its mortal stain.

For Ahmed at the closed border.

For the soldier in his uniform of fire.

For the gunsmith and the armourer,

the boy fusilier who joined for the company,

the farmer’s sons, in it for the music.

For the hook-beaked turtles,

the dugong and the dolphin,

the whale struck dumb by the missile’s thunder.

For the tern, the gull and the restless wader,

the long migrations and the slow dying,

the veiled sun and the stink of anger.

For the burnt earth and the sun put out,

The scalded ocean and the blazing well.

For vengeance, and the ashes of language.

Cormorant, tern,  gull and wader –types of seabirds

Iridescence-a surface of shimmering colours

Fusilier-rifleman

Dugong-large aquatic mammal

She is sad that the animals are being abused by humans and our rubbish, and the world seems to be rebelling against the animals and hurting them when they're in their own environment. They should be safe when they are in their homes, but the humans are destroying the world around us with pollution and rubbish
